Corresponding and like parts are referredto in the following descriptionand designated in the several views of the drawings by like referencecharacters. The machine embodies a suitable frame including side members1 and transverse connecting members 2, 3 and 4. This frame is supportedby means of caster wheels 5 and drive wheels 6 which are mounted uponaxles 7. The'middle transverse connecting member 3 is disposedin ahigher plane than the front member. 2 and the rear member 4 and isconnected with the latter by means of spaced ribs 8 which arelongitudinally adjustab FigureQis asection on the line 2-2 (if oilThegspacegdefineil wast-its forms a receptacle for receiving elegance pcked 11p by the machine and hiss ate orfreceptia'cleis closed at therearby means of an end gate 9fwhich, is pivoted to swing ps 'aidlymdrearwardly at its lower edgic Catches applied to the rear lowercforne'rs of side'me nbers l, eiigaget'lie e'n'd' gate. 9' and normallhold a inged.

The reel18 is rotated to cause its teeth to travel upwardly and rearwardly inthe spaces formed between the teeth 13, and as a result stones lifted bythe teeth 13 are moved upwardly and rearwardly thereover by the teeth ofthe reel 18. A sprocket wheel 21 fast to an end of the shaft of the,reel 18 is connected by meansof a sprocket chain 22 with a sprocketwheel 23 loose upon an axle 7 and in this manner the reel is driven byone of the ground wheels 6. A suitable clutch 24 is provided to connectthe sprocket wheel 23 with the adjacent drive wheel 6 and this clutch isoperable by means of a shifter 25, whereby to admit of throwing the reelinto or out ofaction, as required.

An endless elevator 26 is disposed be tween the teeth 13 and.thereceptacle for receivingthe stones and operates to convey the stonesfrom the teeth 13 to said receptacle. The endless elevator 26 may be ofany preferred construction and, as shown, comprises side chains andslats. A shaft :27 is mounted in the side members 1 adjacent thetransverse member 3 and is provided at its endswith sprocket wheels 28which receive the side chains of the elevator 26. A gear wheel 29 fastto an end of the shaft 27 is in mesh with a gear wheel 30 loose on theadjacent axle 7 and adapted to be connected therewith by means of aclutch 31 which is operable by means of a shifter 32, whereby to admitof throwing the elevator into and out of gear, as re quired. Theprovisionof the gear wheels 29 and 30 causes the upper run of theelevator 26 to travel'upwardly and rearwardly, thereby carrying thestones fromthe teeth 13 into the receptacle at the rear of the ma chineand closed by means of the end gate 9. A pulley 38 fast on the shaft 27supports the endless elevator intermediate the sprocket wheels 28.Sprocket wheels 34 mounted upon the inner side of the members 1 adjacentthe transverse member 2, support the lower portion of the endlesselevator 26, the side chains of which pass around said sprocket wheels Asweep 35 is mounted upon one of the side members 1 and a rein holder 36is attached to said 'side member and supports the driving lines in amanner to prevent interference thereof with the reel 18. An arched bar37 serves to connect the side membersl and incidently provides a guardand elevator. 7

As' the machine is. drawn over the field, the teeth pick upstoneswhichare moved thereover by means of the reel and delivfor thereel ered to the elevator, the latter carrying the stones upwardly andrearv-.'ardly and discharging the same into the receptacle from whichthey are discharged when required by means of the end gate 9. The teeth13 combined with the teeth of the reel 18 operate in the capacity of aharrow to loosen and lighten the soil, as will be readily understood.

hat is claimed is:

1. A machine of the character specified including gathering teeth, areel disposed forwardly of and above the gathering teeth and adapted toeoact therewith, and means by which the gathering teeth and reel may beadjusted with respect to each other and to the ground.

2.111 a machine of the character specified, pivoted gathering teeth, abar disposed beneath these teeth, means for adjusting the bar to raiseorlower the teeth, a reel disposed forwardly of and above the gatheringteeth'and adapted to coact therewith, and means for raising and loweringsaid reel with respect to said teeth and the ground. I

3. A machine of the character specified comprising a frame includingside members and a transversely disposed connecting member, gatheringteethpivoted to said transverse member, an adjusting bar disposedbeneath said teeth to effect vertical adjustment thereof and having itsends bent at a right angle and pivoted to the side members, a baroperating lever mounted upon one of the bent ends of the bar andprovided with an arm engaging the bar, anda notched member cooperatingwith the lever to secure the teeth in adjusted position.
